tension spring 25 causing saidy rodA to noimally engage the notches of the segment 26.

The engine shaft '13 extends rearward from the gear 16 and is connected to the propeller shafts 27 by means of chains 28, the propellers 29 on said shaftebeing thus revolved in the same direction.

From the foregoing construction it is clear how the main planes 5 are moved forwardly and tilted by the actuations of the levers 12. The return or rearward movement `of the planes 5 is caused by air resiste ance thereon. The planes 5, as before stated,

are pivoted to the main frame 1 at the points G, but these pivots are not sufficient to properly guide the movements of the `planes.

Segmental guides 29 are therefore provided. VEach guide 29 is provided with a groove 30 circular in cross section, vand with an integral sleeve 31 rotatablylmounted on an upper longitudinal member of the main frame 1.` Secured to the inner corners of the main planes 5 are spherical studs 32, as

illustrated in Fig. 3, each stud being free to traverse the groove in which it is mounted. The planes 5 are supported by wires 33 connecting the same with a vertical mast 84 l extending upwardly from the plane 2. A

. The operation for manipulating the planes 5 is as follows: When a lever 12 is moved 4forward to cause the rotation of a drum 11, then a wire 9 will wind on the drum and cause one of the planes 5 to move forwardly.

Simultaneously with this action the rear edge of the plane 5 would be depressed which produces a greater air resistance, this causing this side of the machine to be elevated.

The rudder will also be moved by a wire 7 as hereinbefore described. The cooperation of the planes 5 and the rudder 4 is such that Awhen a turn is being made that the proper side of the machinewill be moved, thus maintaining stability.

An .aeroplane Aof the construction asset forth 1s simple of construction and eiiicient While I have shown what I deem to be the preferred form vof my improved aeroplane, I do not wish to be limited thereto as there might be various changes made in the details of construction and the arrangements of parts described without departing from the spirit of the invention, hence I desire to avail myself of such variations and modifications as areV comprehended within the scope of the appended claims.

Having described my invention what I deem as new and desire to secure by Letters p 1. In an aeroplane, a main-frame having upper and lower longltudmal members, os-

c1llatory supporting planes pivoted to said' upper members and extending laterally there- `from, an engine on said frame and propel- 1ers `driven. thereby, drums releasably con- I leCted with the engineushaft, operative connections between said drums and said planes for moving the latter forwardly, and means for oscillatingsaid planes simultaneously with vthe forward movement thereof, substantially as described.

2. In an'aeroplane, a main-frame having upper and lower longitudinal members, os-

cillatory supporting planes pivoted to said upper member and extending laterally therefrom, an engine on said frame and propel- 1ers driven thereby, rotatable drums releasably connected with the engine shaft, operative connections between said drums and said planes for moving the same forwardly, and means for oscillating said planes simultaneously with the forward movement thereof comprising a series of pivoted members connecting the forward and rearward edges planes for moving the same forwardly, and f means for oscillating said planes simultaneously with the forward movement thereof, substantially asfdescribed. i

4. An aeroplane comprising a main-frame having upper and lower longitudinal members and connecting transverse'members and an engine carried by a part of said members, a' pair of propellers having chain con` ioo nections with the engine shaft, a pair of oscillatory main supporting planes pivoted to said upper members and extending laterally therefrom, a pair of rotatable drums relio@l leasably connected with the engine shaft and controlling means therefor, flexible wires adapted to wind on said drums and connected to said planes for moving the same forward, and means for oscillating said planes simultaneously with the forward movement thereof comprising a seriesof inclined pivoted members extending from the forward and rearward edges of the planes to said lower frame members, substantially as described. v

5. An aeroplane comprising a main-frame having upper and lower longitudinal members and transverse connecting members, an

engine carried by a part of said members, a

pair of propellers having chain connections with the engine shaft, a .pair of oscillatory main planes pivoted to said upper longitudinal members and extending laterally therefrom, a pair of rotatable drums releasably connected with the engine shaft and controlling means therefor, flexible wires adapted to wind on said drums and connect to said planes for moving the same forwardly, and means for oscillating said planes simultaneously with the forward movement thereof so that the rearward edges thereof will be lower than the forward edges, substantially as described.

6. An aeroplane comprising amain-frame, an engine mounted in said frame, and propellers driven thereby, drums releasably oonnected with the engine shaft, flexible wires adapted to wind on said drums, oscillatory main planes pivoted to said frame and means for supporting the same, said wires being connected to said planes for moving the same forwardly, and segmental guides rotatably mounted on said frame and connected to the inner corners of said plane, substantially as described.

7. In an aeroplane, the combination with a main-frame, of an engine supported on said frame, a pair of propellers connected with the engine shaft, a pair of oscillatory main planes pivoted to said frame, a pair of rotatable drums, friction cone-gears conneeting said drums with said engine shaft; an independent lever for controlling the cone-gear driving connection and releasement of each drum, flexible wires connecting said drums with said planes, and a brake mechanism for holding said planes in position when the actuating gears are released, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
